Spring Boot 2.0.0.RELEASE java.lang.ClassNotFoundException：org.springframework.aop.framework.AopProxyUtils

Question

我正在使用带有hazelcast的Spring boot 2.0.0.RELEASE版本。

我正在尝试将数据保存到HazelcastInstance，并且无法启动服务器，而我正在获取java.lang.ClassNotFoundException：org.springframework.aop.framework.AopProxyUtils执行。

这是pom.xml

启动服务器时，出现以下异常

有人可以帮我吗？

Answer 1

看来您错过了一个依赖项。 尝试将其添加到您的pom.xml。

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-aop</artifactId>
   <version>${spring-framework.version}</version>
</dependency>  

Answer 2

您必须使用2.0.0.0 spring boot父版本吗？

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
</parent>

如果您将版本2.1.6.RELEASE用于spring-boot-starter-parent ，则此Missing类位于spring-aop软件包中， spring-aop会与依赖关系一起自动包含在其中。

如果必须使用2.0.0.RELEASE，则必须手动添加spring-aop依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>5.1.8.RELEASE</version>
    <scope>compile</scope>
</dependency>

根据您拥有的春季版本更改版本。

另外，您可以尝试添加以下依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>

Answer 3

这很奇怪，但是我删除了存储库，它开始工作了
